Updating Zip archives?

[davido]

I have some Zip archives that contain up to 1000 jpegs and a text file.
I would like to update the text file from time-to-time.
Can anyone suggest the best way of doing this with PB code?

Write the textfile in a seperate file. Changing files in a zip is always difficult, because the format is not designed for something like this.

@GPI,
Thank you for your sound advice.

The only way i know is to unzip the zip make your changes and then rezip.

To help I have written a quick prog available here http://www.purebasic.fr/english/viewtop ... &hilit=zip

@collectordave,

That's extremely kind of you.
I'll look forward to trying it, later.
